Dress Code in High Schools in United State Are you with or against Essay

Dress Code in High Schools in United State Are you with or against - Essay Example Administrations of high schools hold the responsibility of ensuring that their schools remain safe and orderly. With the Education Commission of States, ECS (2014) citing statistics from the National School Board Association estimating the number of guns snaked into American public schools at 135,000, the implementation of dress codes would play a critical role in identifying such persons and thus promote a safe school environment. Raby (2012) documents dress codes that require students to expose their belt lines as significant in deterring the concealing of guns under clothing. Furthermore, it is easier for intruders to be identified in a school that has a dress code (Wilder & Key, 2007). This plays a critical role in identifying any persons who come to school with ill intent. Schools that have implemented dress codes have recorded a decrease in fights and violence. Dress codes improve students’ academic performance. This is because, as documented by Gentile and Imberman (2010), having a standard way of dressing helps students concentrate on their academics. It saves a lot of time spent dressing, especially for adolescent students, thus saving time for studies and sleep, both of which promote academic achievement. Thus, dress codes help schools achieve their academic objectives. Thirdly, schools with dress codes have been noted to promote positive educational environments. Such positive educational environments have been promoted by requiring students to wear uniforms. Wilder and Key (2007) support this argument by giving an account of President Clinton’s 1996 State of the Union address which endorsed the idea of uniforms in schools following findings that school uniforms instilled student discipline, decreased theft and increased resistance to peer pressure. Sharing in the same sentiments, Raby (2012) observes that dress codes in schools reduce teasing among students. This promotes harmony in the school, fostering an appropriate environment

Facial Expression Categorization by Chimpanzees Using Standardized Essay

Facial Expression Categorization by Chimpanzees Using Standardized Stimuli - Essay Example Four experiments were conducted onchimpanzees using a set of standardized, prototypical stimuli created using the newChimpFACS coding system. 1) The first experiment was to determine whether chimpanzees could discriminate the3D facial expression figures in a MOT (matching-to-sample). It was a reproduction ofthe study by study by Parr, Hopkins, et al. (1998) Procedure: Data were collected on experimenting 6 male and female chimpanzees aged11 years and above. They were tested in their home cage. The computer placed in anaudio visual cart was positioned about 30 cms from the cage and the eye of each animalwas about 40 cms from the computer. A joystick was attached protruding 4 cms into themesh. The experiments conducted were: 1) Initial Discrimination of Poser Stimuli 2)Inversion Effect for Facial expression 3) Examining Perceived Dissimilarity usingMultidimensional Scaling 4) Discriminating Facial Expressions using ComponentMovement. Experiment 1:The aim of this initial experiment was to verify whetherthe Poser facial expression stimuli were prominent for the subjects, and whether it couldbe discriminated at high levels of skill and that expressions were dealt with no evidentparent stimulus biases. The analysis showed that 'scream' was the most salientexpression to single out. In fact the subjects reached the final testing criteria for screamsin minimum time. Experiment 2:Experiment 2 revealed a significant inversion effect suggesting a generalconfigural processing strategy for all expressions. Experiment 3:Subjects' pattern of error when differentiating all expressions. Apart from screams and pant-hoots showed much difference based on the identity of thefoil expression. They share the majority of their individual component movements, suchas the bared-teeth display, the presence of these similarities did little to confuseperformance. The MDS analysis provides a statistical interpretation of howexpressions were categorized based on their perceived dissimilarity. Experiment 4:The results showed that for each facial expression, at least one component movement wasseen to
